Usages and impacts of the integration of information and communication technologies (ICTs) in elementary classrooms: case study of Swedish municipality schools

During recent years, many schools have started to implement information and communication technologies (ICTs)-based learning devices (such as laptops, tablets, mobile phones, and active boards) in the classroom settings in order to increase learning outcomes. The aim of this study is to find which activities and outcomes are evident in the usages of computing devices and how those devices aid elementary-level students in their learning activities. The study includes five overt participant observations at some schools in a Swedish municipality including unstructured interviews and explains the findings through activity theory and the Alberta Education Framework for Student Learning . The major activities found were dealing with the (1) educational application assignments, (2) storytelling, (3) report writing and (4) practical interaction assignments. We concluded that ICTs aid students in becoming more concentrated, focus driven, engaged and amused, thus learning becomes more interesting.     

Lessons from ‘a really useful engine’™: using Thomas the Tank Engine™ to examine the relationship between play as a leading activity,imagination and reality in children’s contemporary play worlds

This paper examines Vygotsky’s conception of play as a leading activity in the contexts of children’s contemporary play worlds. Commencing with an examination of the relationship between leading activities and the development of psychological functions, the paper moves into a consideration of the relationship between imagination and reality as a basis for play as a leading activity. The relationship is considered in the context of current discussion regarding the sociology of childhood and the sociology of consumerism to explore the ways in which children’s experiences in digital–consumerist contexts possibly shape learning and development. Drawing on the example of the highly popular character Thomas the Tank Engine?, the paper examines the implications associated with understanding play as a leading activity within contemporary contexts, and how these might relate to existing perspectives on play, pedagogy and curriculum in early childhood education settings.     

Expansive learning across workplace boundaries

The article analyses a collaborative effort of learning across workplace boundaries in a regional learning network of South Savo, Finland. The focus is on the Forum of In-house Development in the network. Our objective is to highlight a dialectical approach to boundaries that draws from the ideas of cultural-historical activity theory. Expansive transformation may be explored through the expansion of socio-spatial and instrumental-developmental boundaries. This is shown through four transitional episodes that reveal the expansion of the object of learning. We argue that crossing the socio-spatial boundary of a workplace is not a sufficient condition, but that new meditational means created at the instrumental-developmental boundary are needed to expand workplace learning and development in challenging and complex regional contexts.
